Question: Riemann Sum Integral refresh

From https://community.home-assistant.io/t/add-force-update-support-to-template-sensor, I think you can “force” a boiler update with

  - platform: template
    sensors:
      boiler_power_in_watts:
        friendly_name: "Kazán teljesítmény Wattban"
        value_template: >
          {% if is_state('binary_sensor.boiler_ww_charging', 'on') %}
            {{ ((states('sensor.boiler_burner_current_power')|float(0)) * 29000 / 100) | round(0) }}
          {% else %}
            {{ ((states('sensor.boiler_burner_current_power')|float(0)) * 24000 / 100) | round(0) }}
          {% endif %}
        attribute_templates:
          hour_last_updated:  "{{ now().hour }}"

Every hour, the attribute value will change, so a new state will be recorded, that should trigger the whole chain.
